Answer:
13 bracelets
Step-by-step explanation:
She has approximately 94 inches of string and she she uses approximately 7 inches of string for each bracelet
she can make 94 ÷ 7 = 13 bracelets with the string she has.
To find if three number are a triangle, the formula is A^2 + B^2 = C^2. This means that when you square the lowest two terms they need to add to the square of the third number.
12^2 = 144
13^2 = 169
144 + 169 = 313
26^2 = 676
Since 313 does not equal 676 these numbers cant be the sides of a triangle.

Answer:
37/5
Step-by-step explanation:
7 2/5 = 37/5
5x7=35
35+2=37
Multiply the whole number and denominator then, add the numerator and put the sum of that back ontop of the denominator
Example:
W N/D DxW=X X+N= Y
W N/D = Y/D
Answer:
Step-by-step explanation:
Given:
To find 
Using trigonometric relations for sums and differences of squares of the ratios.
We know:
Plugging in in the above relation.
Subtracting both sides by 0.75.
Taking square root both sides.
∴ (Answer)
